character as the Blue Licks, that is, salt sulphur. A num- 

 ber of salt springs are found in this formation, also salt wells. 

 At the BLUE LICKS there are several springs, all of which 

 are very similar in composition, according to Professor 

 Peter. The salt wells or deep waters contain chlorides of 

 sodium, potassium, calcium, and magnesium, sulphate and 

 carbonate of lime, impregnated with sulphuretted hydrogen, 

 while the surface springs are simply limestone water with 

 little salt or gas. 



In Keene, Jessamine County, there is a well in the Lime- 

 stone Formation containing a sulphureous salt water, with 

 medicinal properties. Contents, sulphuretted hydrogen and 

 carbonic acid gases, bicarbonates of lime, magnesia, and 

 soda, chlorides of sodium, magnesium, calcium, with potas- 

 sium, and some iron. The water is not so strong as BLUE 

 LICK, containing 16 grains of salt in 1000 grains of water. 

 (Peter.) 



In Scott County there is a well, in this Formation, 

 116 feet deep, the water of which contains chlorides of so- 

 dium, calcium, and magnesium, with the odor of sulphuretted 

 hydrogen. 



Another well, in Harrison County, also in the "Blue 

 Limestone Formation," 105 feet deep, contains a water with 

 sulphureous odor, and sixteen parts in a thousand of saline 

 matter, chloride of sodium, calcium, magnesium, and potas- 

 sium, sulphate of lime, bicarbonates of lime, magnesia, and 

 iron, with some iodine. (Peter.) It resembles Blue Lick 

 waters. 



Other wells, in the same formation, exhibit the same cha- 

 racter of waters ; there being also a number in Lexington 

 with the elements above enumerated. There are none of 

 the waters of the Lime Formation so valuable as the " Lower 

 Blue Lick." (Peter.) At this place the principal spring 

 is near Licking River; temperature of water, 62 F. "The 

 water is of a yellowish-green tint, depositing a yellowish- 

 gray sediment. This color comes from the decomposition 

 of the chemical elements of the water, the hydrogen, oxygen,
